Ela Mean 38.5 mg/can Relative standard deviation = 5.5% H95%C.I. 38.5 mg/bottle ± 2.6 mg/bottle RE= -1.1% Michel Mean= 34.1 mg/can Relative standard deviation = 2.3% H95% C.I. 34.1 mg/bottle ± 1.0 mg/bottle RE= 6.5% Select ALL of the TRUE statements about the statistical analysis of their results. Based on Michel's results, there is a 95% probability that the population mean is in the range of 1.0-34.1 mg/bottle. Michel has better precision than Ela because his relative standard deviation value and true value range (H95%C.I.) are smaller than Ela's. Michel's accuracy is not as good as Ela's because his relative error value is larger. Ela's relative error result indicates her values for the mg/can of quinine in the replicate tonic water samples were closer to each other than Michel's. Ela has better precision than Michel because her relative error value is smaller. Ela has better precision than Michel because her true value range (H95%C..) is larger. Ela's accuracy is not as good as Michel's because her relative standard deviation is larger.

Question
Ela Mean = 38.5 mg/can Relative standard deviation = 5.5% H95%CI= 38.5 mg/bottle ± 2.6 mg/bottle RE = -1.1% Michel Mean = 34.1 mg/can Relative standard deviation = 2.3% H95%CI= 34.1 mg/bottle ± 1.0 mg/bottle RE = 6.5% Select ALL of the TRUE statements about the statistical analysis of their results. Based on Michel's results, there is a 95% probability that the population mean is in the range of 1.0-34.1 mg/bottle. Michel has better precision than Ela because his relative standard deviation value and true value range (μ95% C.I.) are smaller than Ela's. Michel's accuracy is not as good as Ela's because his relative error value is larger. Ela's relative error result indicates her values for the mg/can of quinine in the replicate tonic water samples were closer to each other than Michel's. Ela has better precision than Michel because her relative error value is smaller. Ela has better precision than Michel because her true value range (H95%C..) is larger. Ela's accuracy is not as good as Michel's because her relative standard deviation is larger.
